Nice! I like all decisions here!

Shall I add a run script in the template/package.json?
The idea is now kinda that the editor can detect the .prettierrc and formats the current file on save. What do you think? There were some complaints on having this task in the build steps.

I wouldn't add a run script. To migrate a project to prettier its often enough to do a find . | prettier run once and then rely on the editor picking up the .prettierrc file.

Is there a VSC extension that takes the prettierrc settings into account and let you do that using a command?

yep https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode uses the config file.

I also activated the prettier.requireConfig setting, so that projects without a config file will not be formatted.

One more thing, when prettier handles the 80 chars line length, can we switch off the eslint setting for this? Prettier sometimes cannot split the lines and then eslint complains. We should let prettier do it as good as it can...

wrong checkbox...

[pwambach]

disable eslint line width rule please
